ANNOUNCEMENT: Remote Route Collector (RRC10) at MIX
by Matthew Williams 14 Nov '03

14 Nov '03

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 [Apologies for duplicate mails] Dear All, The RIPE NCC is pleased to announce that the RIS Project's Remote Route Collector, RRC10, is now ready to peer with members at the Milan Internet Exchange (MIX): - ---------------------------------------------- RRC10 is located at the Milan Internet Exchange in Italy. It is the tenth collector to be deployed by the RIS and has been operational since November 2003. RRC10 has an interface on the shared MIX fabric (IPv4 and IPv6 VLANs) and collects routing information from all exchange members willing to peer with us. Our details: - - Peering addresses: 217.29.66.6 (IPv4), 2001:7f8:b:a:1d1:a5d1:2654:6 (IPv6) - - Autonomous system: 12654 - - Email: rispeering(a)ripe.net Please send your peering requests to the address above or use the web form at URL: http://www.ris.ripe.net/cgi-bin/peerreg.cgi Peering Policy: http://www.ripe.net/ris/rrc10.html The Routing Information Service (RIS), which started as a modest RIPE NCC project in 1999, has gradually grown to over 200 peers (IPv4/IPv6) at now eleven data collection points in Europe, Japan and North America. Our mission is to collect BGP routing information over a function of time and make it available to the Community. In essence, this means devising tools that can help ISPs debug problems over time without being limited to a BGP view, and providing RIS raw data regarding the Internet's historical development. For more information about the RIS: http://www.ripe.net/ris/ - ------------------------------------------------ Please send your comments to ris(a)ripe.net.

Announcing RISwhois - RIPE NCC IPv4/IPv6 address to origin mapping
by Rene Wilhelm 06 Nov '03

06 Nov '03

[Apologies for duplicate mails] Dear All, RIPE NCC is pleased to announce RISwhois, a new interface to the BGP data collected by the Routing Information Service (RIS). Using a set of ten Remote Route Collectors (RRCs) installed at different locations around the world, the RIS collects BGP information from over 200 IPv4 and IPv6 peers. RISwhois complements our existing prefix query and looking glass tools by providing a higher level view over an entire set of RRC routing tables. The service looks up IPv4 or IPv6 addresses in the most recently collected full RIB dumps and reports the prefixes and origin AS numbers that match the specified IP, as well as the RRCs on which the prefixes were seen. This can help users in obtaining a quick answer on route visibility (i.e. where is it seen, how widely does it spread) and in assigning origin AS numbers to IP numbers in applications such as traceroute. RISwhois listens to the whois port (port 43) and outputs data in a format very similar to the route objects specified in RPSL. Thus applications that, to date, consult a routing registry, like whois.ra.net, can easily obtain more accurate IP to AS assignments by contacting the RISwhois server, riswhois.ripe.net, instead. For example, a study in the context of RIPE NCC's Test Traffic Measurements found 21% of a set of unique IPs unmatched when using the routing registry vs. only 1% unmatched when using RIS data. For more information see: http://www.ripe.net/ris/riswhois.html Please send your comments to ris(a)ripe.net.

NOTIFICATION: RIS BGP Resets on Tuesday, 4th November
by James Aldridge 03 Nov '03

03 Nov '03

Dear All, RIS Notification: ----------------- All RIS Remote Route Collectors will have their BGP processes restarted tomorrow (4 November 2003) between 12:00 and 18:00 UTC. BGP sessions will be reset which will result in additional BGP update activity in our data. The reason for this work is to improve the validity of collected IPv6 data. Best regards, The RIS Team
